A project is underway to investigate the feasibility of a Performance Proficiency Assessment System that would provide decision makers with information concerning the degree to which Fleet personnel are capable of performing the critical aspects of their jobs. The objectives of this study were to (1) identify surface sonar technician performance measures obtainable from the 14A2 ASW team trainer complex that might provide data useful to NAVY personnel managers, (2) identify procedures for obtaining such data during training exercises, (3) develop appropriate procedures for data analysis and summarization, and (4) evaluate methods of automating the collection of the required information. The following conclusions were reached: (1) Data from the 14A2 complex can provide inputs to an assessment system; (2) procedures can be developed for collecting and summarizing proficiency/deficiency data so that they can be readily understood by personnel managers; (3) procedures can be developed for automating the collection and analysis of the desired information. Experiments will be conducted to determine the degree to which the types of information described in this report would be useful as part of a Performance Proficiency Assessment System.
